IOTA/IOTA-ES occultation update for
(445) Edna / TYC 2414-00419-1 on December 29/30, 2002
visible from China, Khazachtan, S Russia, S Ukraine, S Moldavia, Romania,
frm. Yugoslavia, mid-north Italy, Sardegna, SE Spain and Brasil
Summary
In the night of December 29/30, 2002 a faint 10.8 mag star TYC 2414-00419-1
will be occulted by a 90 km asteroid (445) Edna. This update is based on
USNO/Flagstaff astrometry for the asteroid and recent UCAC star position.
The updated path shows ~8 path width south shift with time 2.2 minutes later compared to
Edwin Goffin's nominal prediction.
Updated path runs over China ~23:16 UT, Khazachtan ~23:17-23:18 UT with Almaty in path ~23:16.8 UT,
S Russia ~23:19 UT with Rostov in path ~23:19.2 UT, S Ukraine ~23:19.5 UT with Odessa in path ~23:19.8 UT,
S Moldavia ~23:20 UT, Romania ~23:20.4 UT, frm. Yugoslavia around 23:20.7 UT with Belgrade in path,
mid-north Italy ~23:21.4 UT, Sardinia ~23:21.7 UT, SE Spain ~23:23 UT and finally NE Brasil ~23:29 UT.
Please check the path chart for details.
Clear sky and good luck !!!

* map: below
* remarks: Path uncertainties are given according to nominal star
position errors and expected asteroid positional accuracy.
Data for the target star:
* name: TYC 2414-00419-1
* constellation: Auriga
* J2000 position [h,m,s; o,',"]: 05h 57m 31.9156s; +35o 03' 34.468"

Target star is in mid-south Auriga, about 2.2 degrees south of 2.7 mag star theta Aurigae = SAO 58636.
!!! IMPORTANT !!!
Purple stars in identification chart are so called 'non-star' objects in GSC; in dense fields
the 'non-stars' are often real stars or blends of close pairs. Be careful about this.
Close finding chart (prepared in GUIDE7):
* occulted star is in center - labeled with cross
* field is 3.0x3.0 degrees
* limiting magnitude is 12.5
* labeled stars have indicated SAO numbers
* remarks:
